I was just told why you didn't see the warning. When you install Emsisoft Anti-Malware through the offer in Emsisoft Emergency Kit, it installs in silent mode, and thus the warning is not displayed. We do plan on fixing this, as obviously we want people to see this warning.

Here's several screenshots. One showing just the warning in the installer, one showing the entire desktop with the installer open and showing the warning, and one showing the file details of the installer with the version number.

The 64-bit version of CCleaner was not effected by this, and is clean. Only the 32-bit version of CCleaner had malicious code injected into it, and that malicious code would only execute on a 32-bit version of Windows.
Changing passwords is not a bad idea, however if you do have a 64-bit version of Windows then you don't have to worry about this particular issue.

Sorry, but this forum is actually for users of the Emsisoft antivirus. I do not think that you will be helped here with your problem if you are not a user of the products of this vendor. Try contacting technical support related specifically to your security product.
With respect

HelloThe program that you have Emsisotf Descrypter Version 1.0.0.51 helped us to describe the extension .arena and then there was another file encrypted with the extension TOP file and then another file with the following extension Macgregor @ aolonline File and then another file with the file next extension ID-E62AD770 File and finally could rescue the file with the original extension.This works for me with smaller files and if I can recover them. I only need a file that is my main database that weighs 2 GB which I could not recover, do I need the license? Or how it works? Could you please support me?regards

Hello! I sympathize with you. Are you sure that your Emsisoft antivirus at the time of the attack was updated and functioned normally? If possible, tell us in more detail, under what circumstances an unauthorized process of encryption occurred? I think this will be interesting to many users.

I cannot recall seeing any dialogue box pop up during installation warning about other installed AV products and compatibility issues. I also follow closely any installation and read every pop up that comes up before pressing "next" etc. I have to say your product did not do as you say it does during installation. Also, as it is a Big issue to the end user, as in my case, a total rebuild required, surely it would be good practice to have a dialogue box with a "Yes" or "No", to continue installation when another AV product is found during install of Emsisoft Anti-Malware.
Perhaps you could show me a screen grab of the warning that should have come up during installation please.
